LONDON -- Sales revenue from Arlo, Nest and other standalone network video-surveillance cameras reached $966 million globally in 2017 and is estimated to grow to $1.1 billion by the end of 2018. The United States was by far the largest country for these camera types, representing about 48 percent of unit shipments in 2017, according to IHS Markit.
"Acceptance of video surveillance for the home has grown, in part because people now have more control over their surveillance systems," said Blake Kozak, principal analyst, smart home and security technology, IHS Markit. "Users of network systems can log in and view footage using their smartphones, share clips via social media or speak to their families through two-way audio-enabled cameras. Cameras are becoming a gateway into the home, expanding their use beyond just security."
Impact of 4K
Some of the biggest trends creating change in consumer video cameras today include improvements in camera resolution and the transition to 4K, analytics and battery-powered cameras. Globally, fewer than 1 percent of standalone network cameras in 2017 were capable of 4K resolution or above, however around 20 percent will possess this capability by 2022. For 2018, 720 pixels or lower is forecast to be the most popular resolution, comprising 48 percent of cameras.
"Camera resolution remains one of the most important measures that vendors use to convey the quality of their products to end-users," Kozak said. "It is a feature consumers understand and are familiar with, due to past experiences purchasing televisions, personal computer monitors, smartphones and other consumer devices."
Most vendors now promote 4K as a solution for wide-area surveillance, claiming fewer cameras can be used to cover the same area. In fact, a digitally zoomed image from a 4K camera is still a 2-megapixel image. This resolution provides a much more usable degradation of resolution quality than high-definition (HD) footage, where digital zooming quickly reduces the image quality below video graphics array (VGA) resolution.
Higher-quality footage also allows for more advanced and reliable analytics to be developed. Two of the biggest barriers to adoption of 4K standalone security cameras are storage capacity and bandwidth. Storage capacities required for 4K footage can also be quadrupled, compared to storing HD footage, which along with bandwidth, raises the cost of 4K cameras. 4K cameras, which have roughly four times the resolution of HD cameras, also require four times the bandwidth, which means recording and management servers and software could also require upgrading to cope with the demands of managing multiple 4K streams.
Deep-learning analytics is still a future trend
Video analytics software can analyze live or recorded video streams to detect, classify and track predefined objects or behavioral patterns. It is used to automate the monitoring process and can be particularly effective in proactively identifying events as they happen and extracting information from recorded video.
For many years, the only way to deliver analytics to consumers in the video surveillance industry was by developing rules-based algorithms. Rules-based analytics rely on a structure of "if-this-then-that" commands, which are designed by developers to help the camera decide outcomes. These rules are fairly rigid by design and, as a result, these types of camera analytics are unable to solve problems they are not already programmed to encounter. However, rule-based analytics are still an excellent method for completing relatively simple tasks quickly and efficiently.
Deep learning, on the other hand, is one of the fastest-growing fields in artificial intelligence. It can enable computers to interpret large amounts of data in the form of images, sound and text. Deep learning analytics have yet to manifest in the consumer market as they are only just emerging in the professional security market. However, IHS Markit expects that as the adoption of cloud-based software services in the consumer industry develops and evolves, deep learning analytics are a natural next step.
Battery-powered cameras charge market adoption
Battery-powered cameras represented about 24 percent of standalone network cameras globally in 2017, which is expected to grow to 28 percent in 2022.
"The introduction of battery-powered cameras has changed the face of the consumer video surveillance industry dramatically over the past five years, as their flexibility and ease of installation has enabled wider adoption of security cameras in the residential sector," Kozak said. "The success of these products has also raised general consumer awareness of home-surveillance systems. Battery life remains a key end-user concern, which is why suppliers are now offering swappable battery-pack accessories. When the camera battery life is running low, the user can simply detach the spent battery pack and immediately replace it with a fully charged replacement. This solution provides consumers with a clear and simplified battery management process."

After NTIA asked for public comments on map improvements in October 2018, the FCC decommissioned the agency's broadband map in early December but did not say whether it will use any of the public's great ideas on its own (largely panned) map.
Mike Zeto, GM of AT&T's Smart Cities division, expects metro areas to adopt platforms to manage multi-departmental IoT solutions once internal processes are aligned and more agencies are involved in smart city applications.
Consumers are buying millions of IoT devices, from smart thermostats and security systems to intelligent entertainment setups and furniture. Yet many of these devices remain isolated because home users are uncomfortable connecting them to each other – or even their WiFi. After all, their WiFi network was probably designed only to handle a few laptops, a gaming system and a couple of smartphones. Now, demand on the network is surging and even though you're delivering 100 Mbps to 1 Gbps, that doesn't necessarily mean the broadband power is in the right place or reaches every corner of a home.
Even if WiFi coverage is sufficient, typing is not on trend. Voice is far more natural, easier and faster. Using a TV keyboard is archaic when more and more households have access to cloud-based voice services, like Amazon Alexa. This webinar will explore how service providers can create a comfortable, truly smart home for consumers – simultaneously driving up margin and loyalty.
